Hi friends and thanks for looking at my thread. I have just upgraded 50 dell computers to 500 gig drives and i have been given the 50 old sata 40 gig drives. There is no data on them that needs proper data destruction so i just want to format them all before i move them on. My question is what is the quickest way to format them all?? Can i do 4 at once if i have a PC with 4 free sata controllers on the board or is it a case of 1 at a time?? I wish to do a proper format and not the quick type. Any help greatly appreciated.
